Your easiest option will be to wrap your XML in a XMLlistCollection which
will throw events you can listen to. If that won't work you can check out
mx.utils.XMLNotifier, mx.utils.IXMLNotifiable, and mx.binding.XMLWatcher but
keep in mind that these classes were hidden for a reason. I'm sure they are
subject to change and they are not documented so only use them if you need
to.

private function changed():void{

}
